Description
Hi
We upgraded our project from Angular 21.1 to Angular 22.2.4.
After that if we try to run/build the project (ng serve/ng build) we get this error:
SyntaxError: The requested module '@jridgewell/sourcemap-codec' does not provide an export named 'encodeRangeMappings'

It's likely that you did not update your dependency (or you override the version in your deps) .
encodeRangeMappingswas introduced in@jridgewell/sourcemap-codec@1.6.0
